As it is the 5th gear is tall,so if you change the rear sprocket to 39 or 38 the top speed on 5th will become lower than stock...
Check at normal 4 k RPM shifting in 3rd and 4th and 5th gear ,and note what is the top speed you are able to achieve, and note the RPM....it will give an insight into what you can expect...if your increase one teeth in front sprocket, or drop three teeth at the rear, the difference will be 500 RPM less for same speed..ie, if you achieved 60 Kmph at 4 K RPM stock,same 60 KMPH will be achieved at 3.5 K RPM.with 14 T at front or 37 T at rear.

This thread has become an excellent knowledge pool in a very short period of time! A bunch of thanks to all contributors.

@psr: I have a question about issue of misfiring in my ZMA (21k kms old, 2007). This issue was non-existent before I gave it for servicing a month ago. My zma now misfires a couple of times when I start the engine using the self-start, usually in the morning when its being started for the first time during the day.

I had read a post of yours (quoted below) and seems like it might be a similar case with my zma, the water probably entered/dampened the sparkplug/seating during the service. And as you have described, the misfiring almost completely goes away after a short ride of about 5-10kms. Can you suggest a way to go about fixing it? I think I start testing with a different spark plug first, but need your opinion.

Another question directed at psr-ji. I am not sure if you remember, couple of months ago, I had told you about my zma's exhaust note being a bit louder than the usual, a bit like bullet-thump. And you had suspected that extra sound might be because of a faulty catalytic converter. Do you think this should be fixed too? I like this sound a lot, and the emission test results look normal, so wondering if its necessary.

psr, do you know what type of paint is used in zma's engine?

Dont know the exact make, but locally people call it as heat resistant paint and a bottle costs between 320~500Rs. Ask Aneesh for more details, he's been experimenting on all types of paints for a while.

Yes, found the culprit.

Did'nt notice anything wrong other than a worn cam... These things are new to me.. So what was the problem???

Here it is 265rs.



Have a look at THIS page.

replies in bold.

Stock paint is non heat resistant,which is why it peals off over time..
You can first clean the head with wire brush and then wash it with water. After drying ,the head can be painted with ay heat resistant paint of your choice.The paint should be capable of withstanding 200 C temperature.

thanks for the info guys,i was wondering if it is available on silvercolor,aneesh could you clarify?also there was a talk to change the gearing of zma to cbz extreme, can anyone post more info on this?

Silver is available but hard to source in our city.

oil leaking issue

guys yday the svc changed sum oil seal near the gear shifter as oil was leaking from there...but still i can see oil leaking from there when i ride for 10kms and stop..there is oil all over and they had also topped up the level...they chaged 90rs for oil seals .. and 50 to top up the oil and 95 for speedo cable.. so guys wht can i do for this oil leaking issue???


pls suggest me a good svc or a mech in mumbai who could solve my problem..

First you have to locate the source of oil leak to stop it...one of the common area is the Neutral connector stub just to the left of gear shifter oil seal..It is a press fit piece which can be pulled off after disconnecting the neutral wire....Before doing it, the oil should be drained, or else the bike must be made to lean to the right /kicker side to prevent oil gushing out of the hole.The unit costs about 30/-. Part marked as 10 with 16 "O" ring is the part to change.

Thanks for the reply sir...can u please provide a pic of it as i can do it correctly ...

90rs for oil seals? Oil seal kit costs only 55rs.
